#64 – Escape Sequences in String Literals

C# allows embedding special (often non-printable) characters into a string literal using an escape sequence.  An escape sequence is a series of characters that begins with a backslash (\), followed by one or more letters or digits.

Here’s an example of embedding several newline characters into a string, so that it’s printed on three different lines.

 Console.Write("First line\nSecond line\nThird line\n");     // 3 lines

Full list of escape sequences in C#:

  • \a  –  Bell (alert)
  • \b  –  Backspace
  • \f  –  Formfeed
  • \n  –  New line
  • \r  –  Carriage return
  • \t  –  Horizontal tab
  • \v  –  Vertical tab
  • \’  –  Single quote
  • \”  –  Double quote
  • \\  –  Backslash
  • (Backslash followed by 0) – Null
  • \xhh  –  ASCII character in hex
  • \xhhhh  –  Unicode character in hex
  • \uhhhh – Unicode character  (4-byte)
  • \Uhhhhhhhh – Unicode surrogate pair (8-byte)

    The string escape for null is not rendering on the page as . There’s also a mixture of hyphen and en-dash.
